If you are flying into Cincinnati, there is an aiport shuttle service which offers a $25 round trip to and from the airport. This is cheaper than a taxi. The name of the shuttle is Executive Transportion. Their number is (800) 990-8841.
If you are making your hotel reservations today, you will need to call the hotel to get the group rate. The hotel number is 513-487-3800. You will not be able to get the group rate through the website.
Thanks,
